The generally limped, overspaced, or odd walk that someone uses when they have a handgun packed in their waistband. It is done to keep the gun's grip from being visible through your shirt, or to keep it from falling down your pantleg if you are wearing loose/baggy pants.
"Heard that fool got busted on a conceal carry charge because he wasnt gunwalkin. Police saw his strap!"
